Serial: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data.

In addition, some pins have specialized functions: Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. Input and Output :Įach of the 14 digital pins on the Uno can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. It also has 2 KB of SRAM and 1 KB of EEPROM (which can be read and written with the EEPROM library). The ATmega328 has 32 KB (with 0.5 KB used for the bootloader). A properly configured shield can read the IOREF pin voltage and select the appropriate power source or enable voltage translators on the outputs for working with the 5V or 3.3V.

IOREF. This pin on the Arduino board provides the voltage reference with which the microcontroller operates.

3V3. A 3.3 volt supply generated by the on-board regulator.

Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage your board. The board can be supplied with power either from the DC power jack (7 – 12V), the USB connector (5V), or the VIN pin of the board (7-12V). 5V.This pin outputs a regulated 5V from the regulator on the board.You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin. VIN. The input voltage to the Arduino board when it’s using an external power source (as opposed to 5 volts from the USB connection or other regulated power source).If using more than 12V, the voltage regulator may overheat and damage the board. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable. The board can operate on an external supply of 6 to 20 volts. Leads from a battery can be inserted in the Gnd and Vin pin headers of the POWER connector. The adapter can be connected by plugging a 2.1mm center-positive plug into the board’s power jack. The power source is selected automatically.Įxternal (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The Arduino Uno R3 can be powered via the USB connection or with an external power supply. The pin configuration is identical on all three processors. Note: The Arduino Uno R3 reference design can use an Atmega8, 168, or 328, Current models use an ATmega328, but an Atmega8 is shown in the schematic for reference.

The Uno is the latest in a series of USB Arduino boards, and the reference model for the Arduino platform for a comparison with previous versions, see the index of Arduino boards. The Uno and version 1.0 will be the reference versions of Arduino, moving forward. “Uno” means one in Italian and is name to mark the upcoming release of Arduino 1.0. Revision 2 of the Uno board has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU mode. Instead, it features the Atmega16U2 ( Atmega8U2 up to version R2) program as a USB-to-serial converter.

The Arduino Uno R3 differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. It contains everything need to support the micro-controller simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get start. It has 14 digital input/output pins (of which 6 can be used as PWM outputs) 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button.

Serial.The Arduino Uno R3 is a micro-controller board base on the ATmega328.
